| Claim: | 1. A system for providing a big data-based AI automatic allocation matching service using taxi demand prediction, the system comprising: a user terminal inputting a current location and a destination to call a taxi, and receiving and outputting a vehicle number and an expected arrival time of the called taxi; a taxi terminal receiving a taxi call signal which is matched with automatic allocation in response to a taxi call from the user terminal, and when outputting an approval event in response to the received taxi call signal, starting destination guidance to the current location of the user terminal; and a matching service providing server including a big datafication unit which maps at least one taxi call signal on a location, time, and day of week, stores it as an accumulated history log, and builds big data, a prediction unit which performs data mining on the big data to execute taxi demand prediction based on the taxi call signal corresponding to the location, time, and day of week, a transmission unit which transmits a taxi demand amount that is predicted on the location, time and day of week where the taxi demand prediction is executed, to the taxi terminal, a matching unit which automatically matches a taxi terminal located at a shortest distance from a current location of the user terminal, when receiving the taxi call from the user terminal, and an alarm unit which transmits the taxi call signal to the taxi terminal matched by the matching unit and transmits the vehicle number and the expected arrival time to the user terminal when receiving an approval event. |
| Claim: | 2. The system of claim 1, wherein the matching unit calls the taxi terminal located at a shortest distance from the user terminal with at least one taxi call list and an empty car list as input values by using an optimal algorithm for an assignment problem through which an optimal solution for the assignment problem is obtained. |
| Claim: | 3. The system of claim 2, wherein, to increase a speed of obtaining the optimal solution for the assignment problem, calculation of an optimized approximate solution is performed using a simulated annealing. |
| Claim: | 4. The system of claim 1, wherein the matching unit selects and matches one taxi terminal in response to one taxi call from the user terminal. |
| Claim: | 5. The system of claim 1, wherein the taxi terminal is a plurality of taxi terminals held by a plurality of taxi drivers, and the matching service providing server further includes, an update unit which updates an empty car list in real time so that the empty car list moves to a drive list, when the plurality of taxi terminals accept the call signal of the user terminal or when a meter mounted in a taxi starts counting. |
| Claim: | 6. The system of claim 1, wherein the taxi terminal is a plurality of taxi terminals held by a plurality of taxi drivers, and the matching service providing server further includes, an oversupply alarm unit which figures out real-time locations of the plurality of taxi terminals, and when a difference between the taxi demand amount that is predicted on the location, time and day of week where the taxi demand prediction is executed, and a taxi supply amount that is figured out in real time on the corresponding location, time and day of week exceeds a preset error range, transmits an alarm to the plurality of taxi terminals so as to block an entry to the location where the taxi demand prediction is executed. |
| Claim: | 7. The system of claim 1, wherein the big datafication unit performs pre-processing including mapping at least one taxi call signal on a location, time, and day of week and storing of raw data corresponding to an accumulated history log in a distributed and parallel manner, cleaning of unstructured data, structured data, and semi-structured data included in the stored raw data, and classifying as meta data, and performs analysis including data mining on the pre-processed data. |
